In silico information with the current (as of September 2010) number of genes mapped and predicted for the porcine genome derived from e!Ensembl (http://www.ensembl.org/Sus_scrofa/Location/Genome webcite). Each gene category has been added together to show the total number of genes assigned to each chromosome. The table shows individual porcine chromosome size in Mbp [52] and length sequenced in Mbp. The predicted gene density of each chromosome was calculated by: the total number of genes/chromosome size. The higher the gene density value, the more gene dense the chromosome.
